Monitoring Forest Resilience: A Methodological Framework for Generating Cross-Calibrated Long-Term Landsat Datasets
Submitted: 09 October 2026 You are already at the latest version Forests worldwide face intensifying natural and anthropogenic pressures that progressively erode their resilience, bringing them closer to abrupt, potentially irreversible shifts. Such loss of resilience can manifest as critical slowing down (CSD), a phenomenon characterized by slower recovery rates.
Preferential nitrogen retention characterizes current eutrophication in United States lakes
Abstract The relative retention of nitrogen (N) and phosphorus (P) in lakes and their roles in nutrient cycling remain debated. Although the United States has implemented long-term P control measures in lakes, inexplicable eutrophication exacerbation still reoccurred over the past two decades. Here we geographically track and analyze the nutrient retention changes of 121 lakes in the USA during 2012-2022 using a combination of machine learning and Bayesian hierarchical methods.
Gradual vs. sudden collapse: What magnets teach us about climate tipping points
Some of Earth's largest climate systems may collapse not with a bang, but with a whimper. Surprisingly, experiments with magnets are helping us understand how. We now widely accept that greenhouse gases and the way we use natural resources are putting enormous stress on the world's climate and ecosystems.

As I See It: We need a different Christmas essay
For too long, the primary holiday essay widely printed has been "Yes, Virginia, There is a Santa Claus." I dislike this essay. It belittles and insults skeptics, those who use science and reason to gain knowledge and who base their ethics on kindness and empathy for all sentient beings, not on arbitrary rules. Skeptics do not have “little minds,” as the essay asserts. Instead, the essay favors those who claim that faith, revelation, authority and tradition are sources of knowledge.
Culture drives success, DEI is essential to culture
CUNA Vice President of Diversity, Equity, and Inclusion (DEI) Samira Salem hosted a panel discussion Thursday on the present and future of DEI, part of United in Sustainability’s sixth annual summit for credit unions. The event featured a variety of events focused around building resiliency through sustainable actions. Salem moderated a panel on whether DEI is a “fad” or something more permanent.
CFPB’s Chopra grilled on bureau’s regulatory approach
CFPB Director Rohit Chopra appeared before the House Financial Services Committee Wednesday and will appear before the Senate Banking Committee today to deliver the bureau’s semi-annual report to Congress. During Wednesday’s hearing, Chopra was questioned on the bureau’s rules to implement Sections 1071 and 1033 of the Dodd-Frank Act.
What is credit utilization ratio?
Your credit utilization ratio is a percentage of how much credit you’re using compared to your total credit limit. It’s an important credit score factor, so knowing how to calculate and monitor it is useful to build and maintain a good credit score. Your credit score, which is a snapshot of your credit health, is based on certain information in your credit report. To create a credit score, credit scoring models look at relevant information in your credit report and place them into factors.
Ecological doom-loops: Why ecosystem collapses may occur much sooner than expected
Around the world, rainforests are becoming savanna or farmland, savanna is drying out and turning into desert, and icy tundra is thawing. Indeed, scientific studies have now recorded "regime shifts" like these in more than 20 different types of ecosystem where tipping points have been passed. Around the world, more than 20% of ecosystems are in danger of shifting or collapsing into something different. These collapses might happen sooner than you'd think.

Is the Amazon rainforest on the verge of collapse?
Sprawling 5.5 million square kilometres, the Amazon rainforest is the largest of its kind and home to about one in ten of all known species. To date, at least 40,000 plants, 2,200 fish, 1,200 birds, 400 mammals, 400 amphibians, and 375 reptiles have been scientifically classified in the region, not to mention nearly 2.5 million insect species. The Amazon has existed as a dense and humid rainforest teeming with life for at least 55 million years.
Climate researchers: consider standing for office - I did
CORRESPONDENCE 30 November 2021 With the COP26 climate summit receding in the rear-view mirror, in many regions it is the decisions made by local councils that are crucial to meeting national carbon-reduction targets. That’s why, five years ago, after a career as an environmental-systems researcher, I decided to devote more time to politics in my home town.

One-fifth of ecosystems in danger of collapse - here’s what that might look like
One in five countries are at risk of their ecosystems collapsing, threatening more than half of global GDP (US$42 trillion, or £32 trillion), according to recent research. This scary sounding statistic raises all sorts of questions. What does “ecosystem collapse” actually mean? What causes an ecosystem to collapse and how do we know when it’s happened? Perhaps most important of all, what comes next?
Huge ecosystems could collapse in less than 50 years - new study
We know that ecosystems under stress can reach a point where they rapidly collapse into something very different. The clear water of a pristine lake can turn algae-green in a matter of months. In hot summers, a colourful coral reef can soon become bleached and virtually barren. And if a tropical forest has its canopy significantly reduced by deforestation, the loss of humidity can cause a shift to savanna grassland with few trees.
Regime shifts occur disproportionately faster in larger ecosystems
Abstract Regime shifts can abruptly affect hydrological, climatic and terrestrial systems, leading to degraded ecosystems and impoverished societies. While the frequency of regime shifts is predicted to increase, the fundamental relationships between the spatial-temporal scales of shifts and their underlying mechanisms are poorly understood.
Grow Deposits and Have a Strong Payments Strategy
The diversion of funds from checking accounts to such alternative accounts as PayPal, Amazon, Playstation, health savings accounts and robo-advisor tools is negatively impacting credit unions by diverting money away from checking accounts, according to Tony DeSanctis, senior director for CUES Supplier member and strategic provider Cornerstone Advisers, Scottsdale, Arizona.
China's polluted soil and water will drive up world food prices
China's pollution crisis means the world's most populous country will be increasingly reliant on food imports, and the consequences will be global, says new study China’s push for more intense farming has kept its city dwellers well-fed and helped lift millions of rural workers out of poverty. But it has come at a cost. Ecosystems in what should be one of the country’s most fertile regions have already been badly damaged – some beyond repair – and the consequences will be felt across the world.
Does sustainable palm oil exclude small famers?
Among Ghana’s small-scale farmers, there’s a saying that if your cocoa crop fails, you may as well go back and tend your oil palm. That’s because oil palm is more resistant to pests and diseases, and provides a regular harvest throughout the year – as long as it is looked after properly, which is rare, according to Rosemary Addico who runs a programme supporting farmers.
China farming boom has left ecosystems in danger of total collapse
China’s push for more intense farming has kept its city dwellers well-fed and helped lift millions of rural workers out of poverty. But it has come at a cost. Ecosystems in what should be one of the country’s most fertile region have already been badly damaged – some beyond repair – and the consequences will be felt across the world.
